Title: Digital modulator
Inventor: HORI YOSHIHIRO
IPC: H03M7/14
Filed: 1999-04-09
Abstract: PROBLEM TO BE SOLVED: To suppress the circuit scale of a digital modulator. SOLUTION: Each of a discrimination section 40 and a selection section 50 is provided with 8 modulation units, and each unit corresponds to each of 4-bit scramble patterns having no symmetry. An offset setting section 28 compares a peak level from a peak hold section 26, that is, a sign of a 1st peak DSV with a sign of a reference peak DSV from the discrimination section 40 sums the both after inverting the sign of the 1st peak DSV when both the signs are coincident and gives the result of the sum as a 2nd peak DSV to the discrimination section 40. The discrimination section 40 discriminates a 2nd peak DSV whose absolute value is smallest among 2nd peaks DSV from the 8 modulation units. Furthermore, the selection section 50 selects prescribed code data from the 8 modulation units but inverts the code data when the offset setting section 28 inverts the code.

Title: Optical communication device
Inventor: HANIYUUDA KEN
IPC: H04B10/00
Filed: 1984-05-25
Abstract: PURPOSE:To reduce considerably the power consumption in an optical communication system by providing a constant current-constant voltage converting circuit in an optical repeater. CONSTITUTION:A constant current-constant voltage converting circuit 41 receives a small current I from a constant current source 1 through a conductor C1 and generates a certain voltage berween a Zener diode 412 and a resistor connected in series to this diode 412, and this voltage is supplied to a signal amplifying circuit 42. Even if the feeding current I is changed, the voltage supplied to the signal amplifying circuit 42 is made constant by a transistor TR411. In this case, the power consumption of optical repeaters 4 and 7 is not dependent upon the feeding current and is constant, and the power loss in the conductor is proportional to the square of the feeding current, and the supply voltage is dependent upon the feeding current. Consequently, the power consumption is reduced considerably if elements such as a communication distance, the power consumption of repeaters, etc. are taken into consideration to set an optimum feeding current.

Title: Confirming circuit for delivery and receiving of object to be conveyed in conveyor
Inventor: GOMI MICHITAKA
IPC: B22D11/16
Filed: 1981-07-06
Abstract: PURPOSE:To detect and confirm deliverying and receiving automatically by deciding the delivery and reception at the point of the time when the respective running speeds of the 1st and 2nd motors are equal and the load current of the 2nd motor is larger than the current of the 1st motor. CONSTITUTION:When a dummy bar 2 is conveyed, the running speed of a motor 12 is higher than that of a motor 11, and the speed of a chain 16 is higher than the moving speed of the bar 2. The bar 2 is conveyed at a higher speed by the pawls 17a of the chain 16. If the bar 2 is delivered and received in such a way, the load current of the magnitude required for conveying the bar 2 flows in the motor 12, and the speed of the motor 12 drops. The load of the motor 11 decreases and its speed increases. The speeds of the chain 16 and containing pinch rolls 9, 9 are made uniform so that the running speed of the motor 11 and the running speed of the motor 12 are made equal. Therefore, comparators both emit ''1'' signals, and the confirmation signal for the delivery and reception is emitted.
